PROBLEM

 

PROBABLE CAUSE

 

REMEDY

Weak beverage.

 

1. Type of paper filter

 

BUNN paper filters should be used

 

 

 

 

for proper extraction

 

 

2. Coffee or tealeaves

 

For coffee, a sufficient quantity of

 

 

 

 

fresh drip or regular grind should

 

 

 

 

be used for proper extraction. For

 

 

 

 

tea, a sufficient quantity of fresh,

 

 

 

 

loose tea leaves should be used for

 

 

 

 

proper extraction.

 

 

3. Sprayhead

 

Bunn-O-Matic sprayhead should

 

 

 

 

be used to properly wet the bed of

 

 

 

 

ground coffee or tealeaves in the

 

 

 

 

funnel

 

 

4. Funnel Loading

 

The BUNN paper filter should be

 

 

 

 

centered in the funnel and the bed

 

 

 

 

of grounds or tealeaves leveled by

 

 

 

 

gently shaking.

 

 

5. Water temperature

 

Empty the server, remove its cover,

 

 

 

 

and place the server beneath the

 

 

 

 

sprayhead. Place empty funnel over

 

 

 

 

the server entrance (not in the funnel

 

 

 

 

rails). Press brew. Check the water

 

 

 

 

temperature immediately below

 

 

 

 

the sprayhead with a thermometer.

 

 

 

 

The reading should not be less than

 

 

 

 

195°F (90.5° C).

 

 

6. Incorrect recipe

 

Consider adjusting brew volumes,

 

 

 

 

dilution volumes, dilution delay and

 

 

 

 

pulse brew routines. Contact Bunn-

 

 

 

 

O-Matic for suggestions.
